PIERCE Sept. 22, 1953 C APPARATUS FOR FEEDING AUXILIARY LIQUIDS TO INTERNAL-COMBUSTION ENGINES Filed May 11, 1950 Tb ENGNE \k MANIFOLD 1 79.] w fi il ATTORNEY Patented Sept. 22, 1953 UNITED STATES PATENT .Y E' $.v QE. F DI G. UX AR LIQUIDS T INTERNAL-COMBUSTION ENGINES '4 Claims.

This invention relates to filling apparatus'for containers of liquid which is dispensed in accordance with the operating requirements of an internal combustion engine or the like.

The invention has particular reference to an inverse oiler which includes a device acted upon by the vacuum in the manifold of an internal combustion engine which serves to draw upon lubricant or other liquid disposed ina container mounted adjacent to the engine. The device is customarily called an inverse oiler because the lubricantor other liquid is fed to th'e'u'pper part of the cylinders in inverse proportion to the degree of vacuum. Thus, when the vacuum is high, the amount of lubricant drawn is less and vice versa A lubricating system of this type was described in my U. '5. Patent No. 2,558,979.

As the supply of the liquid in the container becomes exhausted, it must obviously be repleni'shed, It is undesirable to'permit or require dismantling of the apparatus such as by removal of the container to permit refilling. The reason therefor is that the apparatus is obviously subject 'to running shocks and vibration when used in automobile structures, and the container should be so secured to the apparatus as to resist accidental displacement.

With the foregoing in mind, I have devised an apparatus of the above type which permits a rapid filling of the container without removing it from the remainder of the apparatus. This is accomplished by means of a metal collar fitted around the container and provided with a laterally disposed opening communicating with the interior of the container. Means are further provided for exhausting the air from the container by the operation of the engine at the same time that the liquid is being poured therein. As a consequence, the opening through which the liquid or fluid is being poured may be made relatively small, and the fluid will nevertheless pour freely and speedily without bubbling or the like.

The invention will be further understood from the following description and drawings in which:

Fig. 1 is a front elevational view, partly broken away and in cross-section, illustrating the filling device as used in connection with an inverse oiler, the cross-sectional parts of the filler being viewed as taken along the lines ll of Fig. 2.

Fig. 2 is a top plan view of the composite structure.

Fig. 3 is a fragmentary, enlarged view as taken along the lines 3-3 of Fig. 1.

The container may be approximately of a quart size or more and may contain a lubricant 2 or any otherliquid to be'supplied to an engine or the like in accordance with its operatingrequirements. The container Iii may be formedof glass if desired and is provided with the usual threads ll. These threads are engaged by corresponding threads of a metal collar 12 which embrace the neck of the bottle. The specific form of container ll! illustrated is provided with an annular head 13 which may be used for more 'or less permanently securing the container to the collar i2- so as not to rely solely upon the threaded engagement in accordance with the disclosure'zo'f a patent application which I am concurrently filing herewith and relating to the mounting of such containers. In the said application,Seria1 No. 161,450, filed May 11, 1950, I'described the use of arms connected to the collar and arranged to engage the bead l3, but illustration thereof in the present application is considered unnecessary to an understanding of the invention. In any event, the above mentioned securing or -con nection between thecontainer neck and the collar renders it extremely inconvenient to remove the container each time itis to be refilled. Even in the absence of such more or less permanent connection,'it is undesirable to require. unscrewing of the container from the collar each time the fluid is to be replenished. Accordingly, the collar I2 is formed with a cut-out M through its wall,

'which cut-out communicates with an externally accessible chamber [5. Chamber I5 is provided with a filler opening which is normally covered by the cap l6. Cap I6 is hinged to an outer wall of chamber l5 and is urged into closed position 1' by a spring IT.

The inverse feeding device [8 is acted upon by the vacuum existing in the manifold of an operating internal combustion engine. This vacuum is applied through conduit I9 to the interior of member I3 so as to cause diaphragm 20 to assume various positions of elevation depending upon the degree of the vacuum. A valve mechanism is connected to diaphragm 20. At the same time, the vacuum draws up liquid from container [0 through tube 2|, such liquid flowing through the valve mechanism and through the conduit l9. Further details of operation of such an inverse feeding device are found in U. S. Patent No. 1,883,110.

Base member 22 of member I8 is provided with an opening 23 which permits the passage of air. I have taken advantage of the presence of opening 23 in accelerating and facilitating filling of container 10 when the liquid supply must be replenished. These advantages are realized by operating the engine during filling of the container 10 through chamber [5 of collar l2.

It will be recognized that when the motor is running, liquid may be poured in through chamber I5, and the air displaced by the liquid will be drawn out through opening 23 and conduit l9. Accordingly, such displaced air will not tend to flow through chamber 15, will not cause bubbling, and will not interfere with rapid filling of the container. This method of filling the container is considered to be a portion of the instant invention and is therefore claimed herein together with the apparatus.

The metal collar I2 is adapted to support the liquid feeding member I8 as by means of screw holes 24 formed in the top edge of the collar. The integral and laterally extending projection, the hollow of which forms chamber [5, extends vertically higher than the remainder of the collar and provides a convenient and accessible openin through which the liquid may be poured into the container.

What is claimed is:

l. Filling means for an open-mouthed container having the mouth thereof covered by a liquid feeding apparatus, said filling means comprising a collar secured to the mouth of the container and adapted to support the liquid feeding apparatus, a laterally extending projection formed integrally with said collar, said projection being hollow so as to form a chamber and the wall of said collar adjacent said projection being formed with an opening communicating with said chamber, and a closure cap for said chamber.

2. Filling means for an open-mouthed container having the mouth thereof covered by a liquid feeding apparatus, said filling means comprising a metal collar secured to the mouth of the container and adapted to support the liquid feeding apparatus, a laterally and upwardly extending projection formed integrally with said collar, said projection being hollow so as to form a chamber and the wall of said collar adjacent said projection being formed with an opening communicating with said chamber, and a spring closed cap for said chamber.

3. Filling means for an open-mouthed container having the mouth thereof covered by a liquid feeding apparatus, said filling means comprising a metal collar having internal threads for securing it to the neck of the container, a late rally and upwardly extending projection formed integrally with said collar and above the threads thereof, said projection being hollow so as to form a chamber and the Wall of said collar adjacent said projection being formed with an opening communicating with said chamber, and a closure cap for said chamber.

4. The combination with an inverse liquid feeding device for an internal combustion engine operated through vacuum produced by the engine so as to draw liquid from a container thereof, of filler means for said container, said filler means comprising a metal collar adapted to be secured to the mouth of the container and supporting said liquid feeding device, a laterally extending projection formed integrally with said collar, said projection being hollow so as to form a chamber and the wall of said collar adjacent said projection being formed with an opening communicating with said chamber, and means to apply the vacuum produced by the engine through said collar to the container so as to exhaust air from the container as liquid is poured into said chamber.
